Replace copy with move

[HenriquePreto]

Issue: https://github.com/inductiva/tasks/issues/1323

Idea: First we download inputs and remote assets into /workdir/<task-id>/sim_dir folder, then rename the folder to /workdir/<task-id>/output/artifacts when creating the artifacts to avoid extra copying.

Folder structure before:

/workdir/hvo3je8bdf5ux1qcc1u3ck61f
├── sim_dir
│   ├── dummy.py
│   └── hello.txt
└── output
    └── artifacts
        ├── dummy.py
        ├── system_metrics.csv
        └── hello.txt

Folder structure after:

/workdir/ey3g6jtuaxvkujcqodc6y2kft
└── output
    └── artifacts
        ├── dummy.py
        ├── system_metrics.csv
        ├── output_update.csv
        └── hello.txt

I also deleted the MPIExecuter class since it is no longer used.

I added some logs to my local task-runner and ran this script using my local web API:

import os
import pathlib
import shutil
import inductiva

dir_name = "input-dir"

os.makedirs(dir_name, exist_ok=True)

pathlib.Path(f"{dir_name}/hello.txt").write_text("Hello, world!\n")

custom_simulator = inductiva.simulators.CustomImage("docker://python:3.11-slim")

mg = inductiva.resources.machine_groups.get_by_name("hpmac")

task = custom_simulator.run(dir_name, on=mg, 
                            commands=["touch test.txt"],
                            remote_assets=["test-print-dirs/dummy.py"])

shutil.rmtree(dir_name)

task.wait()

The directory structure after copytree is like this:

| /workdir/hvo3je8bdf5ux1qcc1u3ck61f/
|---- sim_dir/
    |----- dummy.py
    |----- hello.txt
|---- output/
    |----- artifacts/
        |---- dummy.py
        |---- system_metrics.csv
        |---- hello.txt

We can't move directly sim_dir to artifacts/ because artifacts/ already exists and sim_dir/ will be created under artifacts/ (e.g, artifacts/sim_dir/dummy.py)

We download and extract the inputs into the <task_workdir>/ folder. Since the inputs are contained within a folder named sim_dir/, they will be located at <task_workdir>/sim_dir:

task-runner/task-runner/task_runner/task_request_handler.py

Lines 520 to 523 in 41d7028

	unzip_duration = files.extract_zip_archive(
	zip_path=tmp_zip_path,
	dest_dir=task_workdir,
	)

Remote assets are downloaded into <task_workdir>/sim_dir to keep all inputs together:

task-runner/task-runner/task_runner/task_request_handler.py

Lines 480 to 486 in 41d7028

	if self.input_resources:
	download_duration = self.file_manager.download_input_resources(
	input_resources=self.input_resources,
	region=self.storage_region,
	dest_path=sim_workdir,
	workdir=self.workdir,
	)
